Laboratory Coating Blade

A laboratory coating applicator uses a metal blade to scrape evenly across the substrate surface, forming a wet film with controllable thickness. It is used for uniform coating and opacity testing of paints and inks, and is suitable for coating preparation and quality evaluation of materials such as paper and plastic films.
Selection
When selecting, consider the compatibility of the substrate type and size with the coating knife width, determine the blade gap specifications based on coating thickness requirements, prioritize stainless steel material to ensure corrosion resistance, choose between manual or automatic models according to the frequency of operation, and verify compatibility with existing laboratory equipment.
